The sparklet bulb is mounted as to constitute a single apparatuscapable of within a casing e which is screwed onto the head being heldin the hand and conveniently applied g of the appartus.

the passage acts as a throttling device. I claim: I Fig. 2 shows adetail. 1. An atomizing apparatus for mouth and denill! tal purposes,comprising in combination a receptacle of such a size as to be adaptedto be held in a hand; another receptacle smaller than thefirst-mentioned receptacle and adapted to hold a fluid under pressure;an attachable and detachable head on said first-mentioned receptacle andso designed'as to allow of connecting the two receptacles with oneanother and having two passages, of which one is adapted to establish acommunication between the interior of said two receptacles; an atomizingnozzle also projecting forth from said head and being connected with theinterior of the first-mentioned receptacle by the other passage of thesaid head; an outletvalve in this other passage; a screw inserted intothe first-mentioned communication where this latter terminates into thesaid first-mentioned receptacleand having in its threaded portion alongitudinal groove for throttling the flow of the fluid under pressureaccording to the position of said screw, this latter being independentof said outlet-valve.

2. An atomizing' apparatus for mouth and dental purposes, comprising incombination a receptacle of such size as to be adapted to be held in ahand; another receptacle smaller than the first-mentioned receptacle andadapted to hold a fluid under pressure; an attachable and detachablehead on said first-mentioned receptacle and so designed'as to allow ofconnecting the two receptacles with one another and having two passages,of which one is adapted to estaban outlet-valve in this other passage; athreaded member inserted into the first-mentioned passage and having alongitudinal groove for throttling the flow of the fiuid under pressureaccording to the position of the threaded member, this latter beingindependent of said outlet-valve and means for turning said threadedmember from the outside of the first-mentioned receptacle. I

3. An atomizer for dental and medical uses comprising a sealedreceptacle containing a medium under high pressure, a liquid containerand an atomizing nozzle, means for securing the receptacle influid-tight relationship to' the liquid container, means for unsealingthe said receptacle and for providing a passage connecting the interiorthereof with the interior of the liquid container, means arranged insaid passage and partly obstructing the same and having means wherebythe degree of said obstruction may be set to a proper value to cause thepressure medium to-escape from the receptacle 'at any desired, pre set,suitably low rate of'fiow, va tube extending from the interior ofthe'container to the nozzle and a manually controllable valve arrangedin said tube.
